One of the things I love about the NY Times are the little NYC stories they publish, sometimes on the editorial page, sometimes elsewhere.  

Yesterday they interviewed New York-based actor John Hawkes in Park City at the Sundance Film Festival. How could such a nice young man play such an excellent villain, they wanted to know. "I think we all have it in us," he said. "You live in New York? You want to slug people every day." 

It's true. 

Yesterday I was buying coffee at a Dunkin Donuts on Third Ave. Taking out my wallet, another patron rushes past me to the counter. On his cell phone. Sticks out his cup and mouthes the word "Milk" to the counter guy. Keeps on with the phone conversation. The clerk pauses our transaction (I guess cause I'm not on a phone?) and adds milk to the guy's coffee and then comes back to me 

This is why, when casting a movie, if you're looking for a good villain, seriously consider hiring a New Yorker.
